A temperature-regulated catalyst-free photoinduced selective carbene C–H insertion strategy was realized to efficiently synthesize spiro-β-lactones and -lactams, which hold considerable promise in drug discovery programs. The reaction shows broad applicability across a range of α-diazo esters and amides with various ring sizes and substituents and has been demonstrated to successfully achieve the late-stage
实现了一种温度调节的无催化剂光诱导选择性卡宾C-H插入策略,可有效合成螺-β-内酯和β-内酰胺,这在药物发现项目中具有广阔的前景。该反应在一系列具有不同环尺寸和取代基的α-重氮酯和酰胺中表现出广泛的适用性,并已被证明可以成功实现天然/生物活性化合物的后期螺环化。获得的产品可以转化为螺氧杂环丁烷、氮杂环丁烷和环丙烷,这些是在药物化学中具有广泛用途的特殊支架。
